Portescap launches new high torque brushless direct current motor for surgical applications

Company says the new high torque brushless DC motor offers improved thermal characteristics and reliability for orthopedic large bone applications

Portescap has launched its newest surgical motor solution for large bone orthopedic powered hand tools. 

The company says this new size 12 (31.5 mm diameter) mini motor is available in 9.6V, 12V and 14.4V versions with cannulated and non-cannulated options, these motors can deliver peak torques of up to 1,720 mNm in a compact envelope. 

Samples are available in less than two weeks to help speed up the crucial design phase when multiple quick iterations are important to finalize the application specs.

These drives are suitable for various applications such as orthopedic drills, reciprocating saws, oscillating saws, sagittal saws and reamers.

In addition, size 12 motors can also be used in robotic surgery applications, surgical screw drivers and exoskeletons.

Portescap’s brushless DC slotted miniature motors for surgical power tools are designed and manufactured using unique process that encapsulates and protect stators windings and electronics from harsh external environments like autoclave and dish wash witnessed by these applications.

In addition, Portescap insulates the windings per the medical safety requirements for hi-voltage protection that is mandatory for surgical powered hand tools.

Portescap has been collaborating with surgical power tool manufactures for more than 20 years to supply miniature motors custom engineered for critical performance.
